Definitions

  • the present invention relates to a paddle wheel, an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel, and a plant comprising said apparatus.
  • the present invention provides an apparatus with improved efficiency for converting the kinetic energy of a liquid flow.
  • this apparatus is able to convert the mechanical energy of a liquid flow into electrical energy or supply this mechanical energy to an operating apparatus such as a mill or the like.
  • Apparatus equipped with paddle wheels interacting with a water flow have been widely used to convert or transfer the mechanical energy of this flow so that it is available for the operation of further energy generating apparatus or apparatus for mechanically processing products, for example for milling cereals or for working metals.
  • these apparatus are equipped with a wheel having a hub for the mechanical transmission of its rotation and a plurality of paddles fixed to its radial periphery so as to interact with the water flow.
  • the hub may be connected to a transmission device designed to transfer the mechanical energy received from the hub to a user apparatus.
  • the document DE202015106402 describes a conventional apparatus with a converging nozzle designed to inject a water jet into the chamber of a paddle wheel in order to rotationally drive it.
  • the problem underlying the present invention is that of improving the mechanical efficiency of a conventional paddle wheel and an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel, while maintaining its traditional appearance.
  • the task of a paddle wheel and of an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel, according to the present invention, is therefore that of solving this problem.
  • one object of the invention is to propose a paddle wheel and an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel, which allows more efficient use of the mechanical energy received from a liquid flow with which it interacts.
  • one object of the invention is to provide a paddle wheel and an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel which may be easily made using known production technologies.
  • Yet another object of the present invention is to propose a paddle wheel and an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel which is structurally simple, easy to use and may be easily adapted to pre-existing installations.
  • 10 denotes overall a paddle wheel for an apparatus for converting mechanical energy of a liquid flow.
  • the paddle wheel 10 has a direction of rotation A and comprises:
  • At least a first one of said arms 12 has:
  • each arm 12 may comprise a deflector 15 which faces the radial opening 14 so as to deflect a fluid flow exiting the radial opening 14 such that it causes a rotation of the paddle wheel 10 in the direction of rotation A.
  • each arm 12 starts an upward trajectory G so as to then exit from the flow F.
  • Each circumferential opening 13 has a direction of extension which may extend circumferentially with respect to the axis of rotation B in a direction directed in a sense opposite to the sense of rotation A.
  • the deflector 15 may have a deflection surface 15a which is curved and which may face the circumferential opening 14 so as to deflect a fluid flow emerging from it.
  • the deflection surface 15a may have a first end aligned with the radial opening 14 and a second end which extends substantially in a circumferential direction with respect to the axis of rotation B, so as to deflect a fluid flow emerging from the radial opening 14 in a direction opposite to the direction of rotation A, so as to push the paddle wheel 10.
  • the internal cavity D may extend at least mainly along a radial direction C with respect to the axis of rotation B.
  • At least one of the said arms 12 and preferably each of the arms 12 has a plurality of internal cavities D which may be arranged alongside each other along the axis of rotation B.
  • the first arm 12 and preferably each arm 12 comprises a plurality of tubes arranged alongside each other along the axis of rotation B and each defining the internal cavity D inside it.
  • Said tubes may have a circular cross-section or quadrilateral cross-section and may be rectilinear.
  • An open end of said tubes may define the radial opening 14.
  • the present invention also relates to an apparatus for converting mechanical energy of a liquid flow, which comprises:
  • the present invention also relates to a plant for milling, for example cereals, which comprises:
  • the paddle wheel 10 engages with the channel so as to intercept a fluid flow which, during operation, flows along it, so that it is driven by said fluid flow in the direction of rotation A.
  • a plant for the production of electrical energy also forms the subject of the present invention.
  • Said plant comprises:
  • a paddle wheel according to the present invention is able to achieve energy efficiency levels much higher than those of conventional paddle wheels, while maintaining a traditional appearance.
  • a paddle wheel in particular allows more efficient use of the mechanical energy received from a liquid flow with which it interacts.
  • a paddle wheel and an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel may be easily manufactured using known production technologies and components which are simple to produce and assemble, without the need for particularly specialized labour.
  • a paddle wheel and an apparatus for converting mechanical energy of a liquid flow comprising said paddle wheel is in fact structurally simple, easy to use and may be easily adapted to pre-existing installations.
